Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465390, here are decompositions:

7 + 465383 = 465390
11 + 465379 = 465390
17 + 465373 = 465390
53 + 465337 = 465390
59 + 465331 = 465390
71 + 465319 = 465390
73 + 465317 = 465390
97 + 465293 = 465390

Showing the first eight; more decompositions exist.
